Around 75 supporters gathered outside an ethics medical centre he was visiting.

Leader Nick Griffin had to warn them not to use violent language to Cameron even though “he might deserve it.”
Cameron was at the centre to sign a “contract for a new NHS” promising increased health spending, a fund for cancer drugs and to trust doctors and nurses.

He said the NHS was “the thing I care about most.”

He told supporters: “I want you to hold us to this. If we do not deliver you van kick us out in five years time.”

He was questioned by knife-crime victim Niel Connelly, 31, who had to wait 30 minutes for an ambulance to arrive when he was stabbed six years ago.

Cameron invoked the hero-cop from TV’s ’Ashes to Ashes’. He said ambulances must get to victims quicker.
